2 Claims.

This invention relates to new and useful improvements in agitator machines and the primary object of the present invention is to provide a machine for holding and agitating filters. in a bath in order to properly clean the filtersand to thereby permit the reuse of filters that are commonly discarded.

Another important object of the present invention is to provide a filter cleaning machine including a vertically rockable member supporting filters at both its ends and a small and compact mechanism for oscillating or rocking the member so that filters supported at its ends will be effectively agitated in a suitable bath or cleanin medium.

A further object of the present invention is the provision of a filter cleaning machine embodying filter holders so constructed as to permit filters to be quickly and readily applied thereto or removed therefrom in a convenient manner.

A still further aim of the present invention is to provide a machine for cleaning filters that is simple and practical in construction, strong and reliable in use, small and compact in structure, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a plan view of the present invention;

Figure 2 is an enlarged fragmentary longitudinal vertical sectional view taken substantially on the plane of section line 22 of Figure 1;

Figure 3 is an enlarged transverse vertical sectional View taken substantially on the plane of section line 3-3 of Figure l; and

Figure 4 is a perspective view of the agitator or rocking member, used in the present invention, per se.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It represents a vat or container having a transverse partition [2 for dividing the vat into two compartments. A pair of side supports or members 14 rise from the side walls of the vat and rotatably support an upper power driven shaft l6 having a central crank portion or off-set portion I8 for a purpose which will later be more fully described.

members 34 and baskets 36 for each vat.

The numeral 20 represents the agitator mem 14- f'orrotation. Washers 26am mounted onth'e end portions 24' and are held close to theside supports by' nuts 23 threaded on the end portions 242 The web portion orcentral part of a substan'* tially U'-sh'apedmember (iii-isfixedby welding-or the liketo the undersurface'oftheshaft' 22. The member 3d is disposed laterally of the shaft 22 and arms 32 integrally formed with the ends of the member dd terminate in ring members 34 that receive baskets 36 having upper flanged portions 38 that rest upon the upper faces of the ring members 34.

The shaft 22 is disposed in spaced parallel relationship to the shaft it and beneath the shaft 46 and both the shafts i6 and 22 are disposed directly above the partition i2.

A bifurcated member or yoke M1 is fixed by welding or the like to the shaft 22 and rises from the shaft 22 to receive the crank portion E8 of the shaft it. As the shaft it rotates, the crank portion I8 will alternately engage the furcations of the bifurcated member ll to oscillate or rock the shaft 22 whereupon the baskets will be raised and lowered in a suitable bath in the coinpartments of the vat Iii.

A supporting wall 42 extends from the vat l0 and supports a motor it that is connected through reduction gearing it to a driven shaft 48. Sprockets 53 and 52 are mounted on the shafts 38 and it respectively, and are connected by a sprocket chain 54.

In practical use of the present invention a suitable cleaning medium or bath is placed in the vat ii] and filters (not shown) are placed in the baskets 36. As the motor 14 operates, the shaft It will rotate to oscillate the shaft 22 and agitate the baskets in the cleaning medium.

The ring members 34 and baskets 36 may be of any suitable shape, for example square or rectangular to conform to the shape of the filters inserted therein.

Obviously, the machine illustrated may be in multiple units, three or more placed side by side with a common upper shaft l6 having a crank portion for each vat and a common lower shaft for all vats having a member 3i], arms 32, ring One of the vats will be used for washing of the filters, another for the rinsing of the filters and the third for the purpose of dipping the filters in a light oil.

A suitable vibrating table may be employed for shaking excess oil from the filters after they are removed from the third vat in the above assembly.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a filter cleaning machine including a power driven horizontal shaft having a crank portion, a horizontal rock shaft supported beneath the power driven shaft for rotation, a bifurcated member fixed to the rock shaft medially of the ends of the rock shaft and disposed transversely of the rock shaft and extending upwardly from the rock shaft, said crank portion being received between the furcations of said member to impart oscillation to said rock shaft during rotation of said power driven shaft, an inverted U- 4 shaped holder fixed medially of its ends to the underside and central part of said rock shaft beneath said member, and means at the ends 01' said holder for holding filters.

2. In a filter cleaning machine comprising a vat, a pair of supports rising from the vat, upper and lower horizontal shafts journaled for rotation on said supports, means carried by the lower shaft for supporting filters, said upper shaft being power driven and including an offset portion, and a bifurcated member fixed to said lower shaft, said offset portion being received between the furcations of said member.
